RICHARD A. HEILENDAY, OF :TEBSEY CITY, NEW JERSEY, ASSIGNOR TO STANDARD OIL DEVELOPMENT COMPANY, A CORPORATION 01' DELAWARE COMBINED TANK CLOSURE AND GAUGE.

Application filed December 31, 1928. Serial 110. 158,881.

This invention relates to improvements in combined tank closures and gauging devices.

with the accompanying drawing, in which Fig. 1 is a vertical section through the improved tank closure, the section being taken .on the line II-II, Fig. 2;

gig. 2 is a top plan view of the closure; an r Fig. 3 is-a perspective view of the-closure cap and gauge stick.

In the drawings, reference numeral 1 denotes a metallic filling neck exteriorly threaded at its ends. The lower end of the neck 1 is screwed into or otherwise fastened upon a tank or other container; the upper end receives an internally screw threaded collar 2. An outwardly extending flange 3,

having perforations 4, is formed on the collar. A cap 5 has a screw connection with the top of the collar 2. A flange 6 on the cap has perforations 4' and overlies the flange 3. A wire or flat seal passes through cooperating perforations 4, 4. The ends of the wire are brought together and held by a metallic wafer 8. When flat seals are used section, through which the gauge stick passes.

Angle pieces 11 are riveted or otherwise secured to the bottom of the gauge stick, making it impossible to completely remove the stick from the cap. The opening 14 is therefore obstructed at all times and liquid can not be introduced or withdrawn through it.

tween the collar 2 and the cap 5. The gasket is firml held inside the cap 5 by reason of the un ercutting of the cap threads. The

neck and collar may be secured together by A gasket 15 makes a fluid-tight seal bea rivet or screw 16, or these parts may be integral. 1

In the useof the device, a container, for example an underground gasoline storage tank, is filled through the neck 1, on which the collar 2 is screwed and securely held-by rivet or screw 16. The cap 5 with cover 10 and gauge stick 11 attached is screwed on the collar until the cap is firmly tightened against gasket 15. The perforations 4, 4

are so positioned on flanges 3 and 6 that a 1 sealing device may be readily passed through a pair of perforations 4, 4'. Whenthis has been done, it is impractical to put in or take out substantial quantities of liquid without breaking the seal. Tampering with the contents of the tank is avoided in this way. Sealing as described, however, does not prevent the gauging of the tank. The cover 10 may be unscrewed and its attached gauge stick 11 examined whenever it is desired to know how much liquid is in the tank.

I claim:

1. In combination with the filling neck of a container, an exterior flange about said neck, acap for said neck and having an opening therein, an exterior flange on said cap, means for sealing flanges against unauthorized opening, a cover for the opening in said cap, and a gauging stick carried by the cover and depending through the filling neck.

2. Apparatus according to claim 1, in

which the flange about the neck is carried by a collar screwed on the neck. I 3. A closure for the filling neck of a container, and comprising a neck-engaging member having an external flange, a cap for said member and having also an external fiange, means for sealing said flanges against unauthorized opening, a threaded boss on the cap fitted with a central opening, a cover arrangedto screw over said boss, a gauging stick sliding through the opening and sub stantially filling the same, said stick being fastened to the cover and fitted with projections to prevent removal of the stick through the opening in the cap.

4. In combination with the filling neck of a container, a cap for the neck, visible means for sealing the cap to the neck, said cap having an opening therein, a cover for said 5 opening, a gauging stick fastened to the cover operable thru said hole and substantially closing, the same and means on the stick to prevent its complete removal.

5. The'combination as claimed in claim 4 in which the cap is provided with a central, 10 externally threaded boss, and said cover is in the form of a cap internally threaded and adapted to screw over said boss.

In testimony that I claim the foregoing as my invention, I aflix my signature.

RICHARD A. HEILENDAY.
